New Vinyl or Old Vinyl ?


I am after a pink Floyd album (  Dark side of the Moon ) . There are some new resissue albums out on the market but there are plenty of older ones being sold . What would be the best one to go for to get the best sound quality . Most of the older ones are asking for more money . 
Any help would be great .
kind regards

This is strictly my opinion, for what it's worth, but I have probably 10-12 different versions of this album. My ranking:

1. Mobile Fidelity UHQR
2. EMI/Toshiba Pro Use Japanese
3. UK 1st Pressing
4. German 1st Pressing
5. Mobile Fidelity regular Pressing
MoFi, is your UK first an A2/B2? Do you find it grainy? I've had some early UKs, not a true first, and the B2 sides always sounded less good than the B3. My go to is generally the UK A3/B3, but like you, I have a bunch of copies. Never owned the UHQR, though- that was always considered one of the ultimate MoFis.
